Ya might wanna sit down for this one, Arrow fans. TV Guide Magazine has learned exclusively that the CW show — which is already exceeding its hot limit with Stephen Amell, Katie Cassidy and Colin Donnell — has just hit a major bull's eye by signing Teen Wolf alum Colton Haynes.

"We were big fans of Colton from Teen Wolf and we are thrilled he's joining Arrow," says executive producer Greg Berlanti of the actor, who is set to begin appearing on the show in 2013 as none other than Roy Harper.

DC Comics aficionados will recognize that name as the young marksman who has been known as, since his debut in 1941, the Green Arrow's sidekick Speedy, Teen Titans member Arsenal, and the Justice League's drug-addicted, one-armed Red Arrow. While details on this iteration's possible secret identity are being kept, well, secret, Haynes' Harper is being described by The CW as "a handsome, street-savvy, teenager from 'the Glades,' the harsh, poverty-stricken portion of Starling City."

The recurring role will provide a love interest for Willa Holland's Thea (who is also nicknamed "Speedy"...hmmmm), as well as some serious juice for the show's growing mythology. According to the network's breakdown on the character, in addition to falling for Ollie's little sister after crossing paths "in an unexpected way," Roy is "destined to become a significant part of her life and an important player in the larger world of Arrow." In other words, this is awesome.

The casting comes just two months after Haynes shocked Teen Wolf fans by tweeting out his decision to leave MTV's hit drama, although there is nothing surprised about how fast it took another show to snatch him up. Seriously, look at the guy.
